Flexible system integration

Mentor MP is a modern DC drive that is based on Control Techniques current AC drive technology, this means that Mentor MP inherits the system integration flexibility, such as:

Galvanic isolation between power and control protects the control circuits and other equipment connected to the drive from the high voltages on the power circuit. This feature is unique on DC drives and is protected by a patent pending

Protection system against poor industrial power supplies and lightning strikes

Integrated drive and motor protection for:

Over current

Over temperature

Phase loss

SCR/Thyristor junction temperature

Feedback loss

Field loss

Armature open circuit

Flexible field control

Internal field controller with intelligent field weakening means that 90% of applications require no additional external controller:

Integrated field control on frame size 1 to 8A

Integrated field control on frame size 2 to 20A

Flux control for enhanced open loop performance

External FXMP25 field control to 25A

Easy upgrade

Mentor MP has been designed to be an easy upgrade for Mentor II. It has the same physical dimensions and power connection layout. Software tools have been developed to easily migrate to the new platform.

The power ratings for the 480V, 575V and 690V configurations are shown below.The continuous current ratings given are for a maximum ambient temperature of 40°C (104°F) and an altitude of 1000m (3,300ft). For operation at higher temperatures and altitudes de-rating is required. Overload of 150% for 30s is available with ambient temperature of 40°C (104°F) up to a maximum of 10 repetitions per hour.
